"God, I'm in better shape now in some ways than I was when I was doing the [1973] Bond film ['Live and Let Die']," Seymour told Closer.

Seymour is one of a group of Hollywood women in their 60s who seem to get better with age. They defy Tinseltown's pressure to stay young-looking by aging gracefully -- letting their wrinkles hang out while maintaining healthful habits and embracing the passage of time.

While admitting to a "minor" eye-lift and Botox injections in the past, Seymour told Closer she now prefers to keep things natural.

"I tried [Botox] and hated it. I'd never do it again," Seymour said. "For me, it doesn't work because I'm an actor and I need to be able to move every part of my face."

"I think I'm being hired a lot because I haven't done all the stuff everyone else is doing," the British actress told the magazine.

She has no diet restrictions but keeps portions small, drinks lots of water, does tri-weekly gym sessions, plays tennis and golf and gets plenty of sleep.

Turning 63 next month, Seymour describes being in her 60s as "pure joy."

Click through to see other celebrity women in their 60s who seem to have found the secret to aging well.

Meryl Streep

Seen here in the same dress she wore in 1979, it would appear Meryl Streep has hardly aged at all. Perhaps her secret is doing what she loves. The multiple-Oscar-winning actress has continued to play a leading lady at 64, defying Hollywood's conventional wisdom that there are no good roles for women over 40. "I'm 60, and I'm playing the romantic lead! Bette Davis is rolling over in her grave!" she joked to Vanity Fair in 2009, when she starred as both Alec Baldwin and Steve Martin's love interest in "It's Complicated." Then, at 62, Streep appeared for the first time on the cover of Vogue, declaring herself the "oldest person" to do so.

Susan Sarandon

For Susan Sarandon, 67, her secret to aging could well be having a relationship with a younger man. Following her surprising split in 2009 with longtime partner Tim Robbins, who is 12 years her junior and with whom she has two children, Sarandon began seeing her much younger business partner, Jonathan Bricklin, 36. After two years of rumors, Sarandon finally confirmed her relationship with Bricklin in March 2012. But it's not just Bricklin's youth keeping Sarandon ageless. His New York nightclub, SPiN, with 17 Ping-Pong tables, also helps to keep her in shape.

Diane Keaton

Like Meryl Streep, Diane Keaton, who turned 68 this past Sunday, continues to find work on the big screen well into her 60s, and unlike in her 20s and 30s when she felt "zoned out," she told More magazine that her life after 60 is in sharper focus. "I feel much more alive," the actress, who also models for L'Oreal anti-aging beauty products, told More in 2006. "When you're younger, you have a tendency to be relieved by fantasies. But now the drama of real life comes charging in."

Helen Mirren

In 2011 British actress and Oscar winner Helen Mirren was 66 when she beat out Jennifer Lopez, Pippa Middleton and Elle "The Body" MacPherson in the L.A. Fitness poll on the female celebrity with the best body. The image of Mirren in a red bikini while vacationing with her husband in Italy at age 63 is not one we will soon forget. But, for Mirren, now 68, a healthy dose of humor could well be the key to aging gracefully. The actress revealed to the women of "The View" that she sucked in her stomach the day she accepted her award from L.A. Fitness. "It was a beautiful thing that these fitness people did, I have to say," she said. "I think it was recognition of the fact that you don't have to be perfect."

Goldie Hawn

One of the original funny girls, Goldie Hawn has relied not only on her sense of humor but her positive outlook to stay young. At 68, she is still the bubbly blonde America fell in love with. But Hawn revealed to Dr. Oz in 2012 that at the height of her fame she battled crippling depression and anxiety. Meditation and therapy helped her regain happiness and led her to the love of her life and partner for more than 30 years, Kurt Russell. While Hawn is grateful for good genes that have kept her looking young, she told Dr. Oz that the real key to aging gracefully is "You just have to love life, you gotta be happy."

Mary Steenburgen

For Mary Steenburgen, 60, the key to aging well may be in constantly learning and growing. The Academy Award winning actress and the star of more than 40 films recently embarked on a new career late in life as a singer and musician after undergoing minor surgery on her arm and discovering her new musical talent. "I went under general anesthetic, and the music started right after that," she told CBS News. Steenburgen, who is married to actor Ted Danson, has since written more than 40 songs and was signed by Universal Music as a songwriter. She also plays the accordion and sang in her latest movie, "Last Vegas." "Hey, it's a miracle to have a career in Hollywood. But it doesn't begin to sum me up," Steenburgen told CBS News.
